Raspberry Pi CAM Mount Remix - LED Ring

prusaprinters

<p>This is a remix of the pi cam front cover from thing:2842300, heavily inspired by user Drse's thing:4226397 (check out that thing for additional details regarding the LED ring and octopi integration!).</p> <p>I found that at max brightness, this LED ring consumes ~334mA@5V, though this was using a USB-powered Arduino as a power supply so that may have been a limiting factor. Either way, double check you have a proper power source or sufficient power supply headroom from your Pi (depending on whatever else is connected to it).</p> <p>The wires in the pictures are stranded 22 AWG (amazon), and connector is JST-XHP 2.54mm (amazon).</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 3 Pro</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div> <p><strong>Resolution:</strong></p> <p>0.2</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>20%</p></div> <p><strong>Filament:</strong> Overture PETG Black</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Printed in PETG per Drse's recommendation, especially since this LED ring gets <em>hot</em> at max brightness. Alternatively, you can drive it at 50% brightness or lower; it only gets warm at this level and I'm guessing should be fine for PLA (though I did not try!).</p> Unfortunately, supports are required, but should separate cleanly if the z gap is decently tuned. The downside is that the entire top part is printed on top of supports, so expect some under extrusion due to a bit of sagging (see pics). Could be compensated using higher flow/extrusion multiplier for top layers, but I didn't bother since this is purely a functional print. <h3>How I Designed This</h3> <p>Using Fusion 360. I took the original camera front cover and slapped a rough copy of Drse's LED ring holder on top of it. I cut off the parts of the ring holder that were larger than the camera cover to avoid additional supports around the cover. I find it still holds the LED ring very firmly.</p> </div></p></p></p> Category: 3D Printer Accessories
